The best gun cleaning kits for a first-time gun owner

A gun cleaning kit is a short list of parts in one case: a brush sized for your caliber, something to move it through the barrel (a rod or a cable), patches and a tip to hold them, and sometimes a bottle of solvent or lubricant. The best gun cleaning kit for you comes down to one question: what calibers do you own? This page answers that for a first-time owner, then ranks five kits by what their makers publish.

Building a whole first kit, not just the cleaning part? Start with our first range kit for new shooters, which puts ear pro, eye pro, a bag and a cleaning kit on one list. If you only own a handgun, our best pistol cleaning kits go deeper on caliber fit and range-bag size.

How we picked these kits

Every kit is scored on our cleaning rubric: caliber coverage (30%), component quality as published, meaning the rod, cable and brush materials (25%), solvent and lube in the box (15%), storage and case (15%), and how easy it is for a first-timer to use (15%). The weights are published on how we pick.

We haven't tested these kits on a barrel, and we won't pretend otherwise. We read each maker's own product page, wrote down the caliber list, the contents, what's in the bottle and the case size, and scored what they publish. Where a maker doesn't list something (a patch count, a case size), the table says so rather than guessing. The ranking follows the scores, with one question on top: which kit is the safest bet for someone buying their first one?

Universal vs caliber-specific gun cleaning kits

Cleaning kits come in three shapes, and the difference is how many calibers they carry brushes for.

• Caliber-specific kits carry the parts for one caliber family. The Otis 9mm Pistol/Rifle kit lists ".357 cal / .375 cal / .380 cal / .38 SPL. / 9mm", and Otis's own FAQ on that page calls it "caliber-specific and optimized for 9mm bores." Fewer pieces, a smaller case (4 x 4 x 2.5 inches), and nothing to sort through.
• Handgun kits cover several pistol and revolver calibers in one case. Real Avid's Gun Boss Pro Handgun kit lists .22, 9mm, .357, .38, .40 and .45, and Hoppe's sells its pistol kit in a "Pistol - All Calibers" version.
• Universal kits carry brushes for handguns, rifles and shotguns. The Otis Elite lists 16 bronze bore brushes from .17 caliber up to a 12/10 gauge brush. Real Avid's Gun Boss Pro Universal covers .22 to .45 caliber handguns and rifles plus 20 and 12 gauge shotguns.

So which one does a beginner need? It depends on what's in the safe, not on how serious you want to look.

• One handgun, no plans for another: a caliber-specific or handgun kit. It's smaller and has fewer parts to lose.
• A handgun plus a .22 rifle, a shotgun, or a family member's guns: a universal kit, so one case covers every bore in the house.
• Not sure yet: a universal kit's extra brushes simply wait in the case until you need them. The trade-off is size and sorting: the Otis Elite has over 60 components and comes in a 15 1/4 x 8 3/4 x 4 1/2 inch bag.

What a beginner actually needs to clean a gun

Strip away the marketing and every kit on this page does the same job with the same few parts. A good way to see the list is to read what one firearm maker asks for. Ruger's manual for its LCP MAX pistol says: "Using a cleaning rod, run a properly sized, solvent-wetted patch through the bore several times. Then attach a solvent-wetted bristle brush to a cleaning rod and run it back and forth the full length of the bore as many times as necessary to remove grease and dirt from the bore and chamber. Clean the bore with dry patches and examine" (Ruger LCP MAX instruction manual). That's one pistol's manual, and yours may differ, but it maps straight onto a kit:

1. Something to move things through the bore. A rod (Real Avid's brass rods, Hoppe's one-piece aluminum rod) or a flexible cable (Otis's Memory-Flex cables).
2. A bore brush in your caliber. Real Avid lists phosphor bronze brushes, Otis lists bronze brushes with the size marked on the stem, and Hoppe's caliber-specific kits list a nylon brush.
3. Patches, plus a jag or slotted tip to hold them. Patch counts vary a lot: Otis lists 10 in its 9mm kit and Real Avid lists 50 in the Gun Boss Pro Universal.
4. Solvent and oil, or one bottle that does both. Some kits include this, some don't (see the table below). A CLP (cleaner, lubricant and preservative) does both jobs; our CLP vs gun oil guide explains when a separate cleaner and oil make more sense.
5. A mat or rag and good light. Not in most kits, but they make the job easier. Our gun cleaning supplies list covers the extras.

Ruger's manual also says "Only a light application of oil is needed to provide adequate lubrication of moving parts and to prevent rust," and that excess oil can "attract particles of dust and dirt." That is worth remembering when a kit arrives with two bottles in it. For the full routine, step by step and safety first, see how to clean a pistol.

How often will you use it? Glock says its pistols should be cleaned and lubricated "After each time it's fired" and "At least once a month, if it hasn't been used in that time" (Glock, Caring for Your GLOCK), and the NRA says "Your gun should be cleaned every time that it is used" (NRA Gun Safety Rules). Our guide to how often to clean your gun covers the details. Either way, a kit you'll open after every range trip should be one you don't dread opening.

Gun cleaning kit contents compared

Here's what each maker lists, side by side. Every value links to the maker's page it came from.

The three differences that matter most to a first-timer, pulled out of those lists:

One honest wrinkle: Otis's contents list for the 9mm kit includes "0.5 fl.oz. Shooter's Choice FP-10 Lubricant Elite," but the FAQ further down the same page says "Most versions of this kit do not include solvents or oils." Check the contents on the listing you buy from before you count on that bottle.

Rod, cable or bore snake?

The kits on this page use two different ways to get a patch or brush through the barrel, and there's a third tool you'll see next to them on the shelf.

• A rigid rod. Real Avid's rods screw together from brass sections, and Real Avid says the handgun kit's rotating handle "prevents rods from unscrewing during bore cleaning." Hoppe's uses a one-piece aluminum rod with what it calls "a ball bearing swivel handle to follow the bore's rifling" (Hoppe's kit page).
• A flexible cable. Otis kits use Memory-Flex cables that you pull through, which Otis describes as "Breech-to-Muzzle" cleaning. Its basic routine is a wet patch, then a brush, then a dry patch, each pulled through the bore, repeated "as needed, until clean."
• A bore snake. One pull-through rope with a brush built in. Hoppe's calls its BoreSnake "A one pass solution" (Hoppe's BoreSnake Den Pistol page). It cleans the bore only, and it comes with no solvent or oil, so it's an add-on rather than a whole kit.

Neither a rod nor a cable is the "right" answer for a beginner; both do the job the manuals describe. If you want the two systems head to head, read Real Avid vs Otis. If you're wondering whether a bore snake alone is enough, our bore snake vs cleaning rod comparison answers it.

Which kit fits which new owner

The ranking above answers "which kit is best overall." Your own answer depends on what you own. Five common starting points, matched against each maker's caliber list:

• One 9mm pistol, and that's it for now. The Otis 9mm Pistol/Rifle kit covers the 9mm family in a 4-inch case. If you'd rather push a rod and want a separate bore cleaner and oil in the box, Hoppe's sells its pistol kit in a ".38, .357, 9mm" version.
• A 9mm pistol and a .22. The Otis 9mm kit doesn't list .22, so it won't cover both. Real Avid's Gun Boss Pro Handgun lists .22 and 9mm among its six handgun calibers. If the .22 is a rifle, a universal kit makes more sense: the Otis Elite has .22 brushes and a 36 inch cable, and the Gun Boss Pro Universal has a brass rod that extends to 32 inches.
• A shotgun in the house too. Only the two universal kits list shotgun gauges. The Otis Elite carries brushes for .410, 28, 20, 16 and 12/10 gauge; the Gun Boss Pro Universal covers 20 and 12 gauge and includes shotgun mops.
• Several handguns in different calibers, no long guns. The Gun Boss Pro Handgun (.22, 9mm, .357, .38, .40, .45) keeps them in one stand-up case. Hoppe's "Pistol - All Calibers" version is the other route, but per Hoppe's it comes with a slotted end and three knob ends rather than a brush.
• You want the bottle in the box so you can clean tonight. The Hoppe's kit (bore cleaner and oil) or either Otis kit (FP-10). The Real Avid kits list neither.

Before you open the kit: the safety steps

What to look for in a gun cleaning kit

1. A caliber list that names your caliber. Not "fits most guns," an actual list. Every kit here publishes one, from the Otis 9mm kit's five calibers to the Otis Elite's 16 brush sizes.
2. A rod or cable long enough for your longest barrel. Real Avid's handgun kit rod is 12.5 inches, a handgun rod. For rifle-length barrels, the Gun Boss Pro Universal's brass rod extends to 32 inches, and Otis includes a 30 inch cable in the 9mm kit and a 36 inch cable in the Elite.
3. Whether solvent and oil come in the box. The Hoppe's kit includes both a bore cleaner and an oil, the Otis kits list FP-10, and the Real Avid kits list neither. A kit without a bottle means one more purchase before your first cleaning.
4. A case that fits where you'll keep it. The Otis 9mm kit's 4 x 4 x 2.5 inch soft case is a range-bag item. Real Avid says its handgun kit's 8 1/4 x 4 1/2 x 1 1/4 inch case suits "a range bag or on a workbench." The Otis Elite's bag is a bench kit, although Otis says the Elite also includes a smaller Otis kit (FG-750) in a round soft case that "packs easily into your range bag."
5. The thread size, for when you add parts later. Real Avid says all Gun Boss Pro Universal components use 8-32 threads, and Otis's chamber flag in the 9mm kit has an 8-32 threaded end. When you buy a replacement brush, match the thread.
6. Enough patches to get started. Ten patches (Otis 9mm) won't last long; 50 (Real Avid Universal) is a better start. With the smaller count, add a pack of patches in your caliber to the first order.
7. Which version the listing is. Hoppe's sells its pistol kit two ways. Per Hoppe's, "The caliber specific kits include a nylon brush, nylon slotted end, and nylon jag," while "The all calibers kit includes one nylon slotted and three knob ends." Hoppe's also sells it in disposable packaging instead of the storage box, so check the listing before you order.

Beginner mistakes with a first cleaning kit

• Buying the biggest kit for one pistol. Over 60 components is great for a mixed household and a lot to sort for one 9mm. Buy for the guns you own or plan to own soon.
• Assuming oil is in the box. Two of the five kits here list no solvent or lubricant. Read the contents, then add a CLP or oil if needed.
• Using a "close enough" brush. A brush for a different caliber group isn't close enough. Match the kit's list to your manual.
• Cleaning with ammunition on the table. Unload, verify clear, and move the ammunition to another room first, every time.
• Too much oil. Glock says "Too much lubrication can affect the pistol's performance," and Ruger's LCP MAX manual says "Before firing, remove all oil and grease from the bore."
• Grabbing a household cleaner. Ruger's manual says caustic or acetone-based cleaners are "NOT RECOMMENDED" and to "NEVER USE AUTOMOTIVE OR PAINT STRIPPING PRODUCTS TO CLEAN YOUR FIREARM." Use a product made for guns and check your own manual.
• Following someone else's manual. Glock says to clean its pistols "When it's brand new, before it's fired for the first time." Ruger says its new LCP MAX "arrived from the factory properly lubricated and ready to fire" and doesn't need cleaning first. Makers differ, so yours is the one to follow.
• Skipping the hand-wash. The North Carolina fact sheet says to wash "your hands, forearms and face after shooting, picking up spent ammunition, cleaning guns" and before eating or drinking. Keep snacks off the cleaning table.
